Renewed April 12, 1339 3 Claims. (01. 40-33) invention relates to advertisi'ng devices pr that typ'e'in which shifting advertisements ar intermittently actuated by a clock mechanism to successively display the same. Heretofore,

such advertising devices have been associated with. aumechahically actuated clock which in addition to indicating the .tim intermittently aetua es the mechanism for shifting the advertis'rhents. With such. constructions there is 16 danger that the resistance of the shiiting vrnech anism will interfere with the accuracy of operation' of the clock. Also, attentionlis required to Wind the clock at certain intervals. Electrica lly operated clocks are now in' quite general use and f5 sta ndardconstructions of small power synchronous v electric motors are being manuiactured therefor. These usually include a step-down gearirig for operating the second hand as well, eage s op i e minut an hou 35' handsl By reason of hqh sh r duqtiqn .inspe d,

the power delivered tothe sccond hand operating shaft is sufiicient ,for operating the shifting mechanism of an advertising display device.

Also, the slow speed is of advantage. I have,

therefore, devised a construction of advertising device which includes an electrically operated clock and a shifting'mechanism for a series of advertisements also electrically operated. While it would be possible to operate both the clock 30 and the shifting mechanism from a single motor,

I preferably employ a second standardized electrio clock motor which is connected in multiple with the motor of the clock and which functions solely for the intermittent actuation of the shifta ing mechanism. The invention, therefore, consists in the peculiar construction as hereinafter set forth.

In the drawing:

Figure 1 is a front elevation of my improved 0 advertising device;

Figure 2 is a rear elevation with the back cover removed to shoW the operating mechanism within the casing;

Figure 3 is a perspective view on a larger scale 45 showing one of the advertising drums, together with the electric motor for intermittently actuating the same;

Figure 4 is a plan view of the mechanism shown in Figure 3;

50 Figure 5 is a section of the end portion of the drum showing a modified means of attaching the advertising panels thereto.

As shown, A is a casing having arranged centrally thereof a clock dial B and above and below 5 this dial the windows C and D through which theaq rnsementsa e displayed. These advertisernerfts are vp referflo ly panels E of a vpoiygo n'al drurfi F which is mounted upon' a shaftG jourl naled in suitable bearihgs within theeasmgor. Qn o'f thesedrumsis mounted in rear. of each window C and D and the two aie connected to each' other to be moved" simultaneously through the rriedium of sprockets .H on the shaft G and (share I connecting said sprockets. The electric clock is of any suitable construction including a '6 synchronous electric motor J which is, mounted within the. casing and with its driven shafts: concentric with the dial B; The specific construction of this. motor forms no part of my invention, but it includes essentially an energizing electromagnet K havingpole pieces L in operative relation to the armature of a rotor enclosed within a housing M which housing also encloses. the step-down gearing for operating the hour, minute andsecond hands. None of these parts are, however, illustrated as all are concealed within the housing M and are not of my invention.

For operating the shifting mechanism I preferably employ a second motor J of similar construction to the motor J, this being also provided with an energizing ma'gnet K, pole piece L and housing M for enclosing the rotor with its armature and the step-down gearing. The shaft for operating the second hand projects out- Ward from the housing M and has mounted thereon one member of. a transmission mechanism through which the drum F is intermittently rotated. This mechanism preferably comprises a plurality of spokes N projecting radially from a head 0- mounted on the second hand shaft. The motor J is so mounted that the plane of rotation of the spokes N is perpendicular to the plane of rotation of the drum F. This drum is provided, at its end which is adjacent to the 40 motor J, with a series of radially extending spokes P secured to a head Q on the shaft of the drum. The arrangement is such that the spokes N during their rotation will intermittently engage with the successive spokes moving the latter an angular distance corresponding to the angle of one of the polygonal sides. The arrangement is further such that the spokes N during rotation will impart a progressively decreas ing velocity to the drum so that when these spokes disengage from the spokes P there is little or no tendency for the latter to continue movement. In other words, the velocity is so low that the slight frictional resistance to the rotation of the drum will almost instantly arrest movement thereof. The motor J is mounted preferably on one side of. the housing A and by means of a bracket member R which is so positioned as to bring the spoked members N and P in proper operative relation.

The electric current from a suitable service connection is conveyed through the cord S into the casing A and then through multiple circuits T and U to the motors J and J. A switch V in the circuit U permits of opening this circuit if it is desired at any time to stop the operation of the shifting mechanism.

With the construction as described, the drums F and F are periodically rotated to successively register the polygonal faces thereof with the windows C and D, and as each of these faces bears advertising matter there will be a succession of displays. As specifically illustrated, the drums are octagonal and are provided with a corresponding number of spokes P, while the spokes N are four in number. This will cause the operation of the drums at fifteen-second intervals or four times to the minute. However, the exact timing of the operation is immaterial.

With the modified construction shown in Figure 5 the panels E are detachably secured to the drum by providing the same with apertures E at their ends which are adapted to be engaged with headed pins F on the spoked drum heads F The arrangement is such that by slightly springing the drum heads F the panels may be engaged with said headed pins and Will lock therewith when said drum heads are released.

What I claim as my invention is:

1. In an advertising device, the combination of a casing having a window opening therein, a drum within said casing adjacent said opening, advertising panels on said drum, a shaft on which said drum is mounted, a continuously operating synchronous electric clock motor having the axis 7 of its driven shaft transverse to the axis of said drum, radially extending spokes mounted on the shafts of said drum and motor, said motor shaft being adapted to successively engage with the spokes of said drum shaft to impart to the latter a periodic rotation for successively registering said panels with said window opening.

2. An advertising device comprising a casing provided with a central clock dial and window openings above and below said dial, an electric clock registering with said dial, polygonal drums within said casing located to successively register the panels thereof with the respective Window openings, shafts on which said drums are mounted, bearings in which said shafts are journaled. a sprocket and chain connection between the shaft of the one drum and that of the other, a radially spoked member mounted on the shaft of one of said drums, a continuously operating synchronous electric clock motor mounted within said casing with its axis transverse to the axis of said last mentioned drum, and radial spokes mounted on the second hand shaft of said motor adapted to successively engage said radial spoked member to periodically rotate said drums to successively display the panels thereof through said window openings.

3. In an advertising device, the combination of a casing having a window opening therein, a drum within said casing including a shaft, drum heads mounted on said shaft, advertising panels extending between said drum heads and headed pins on said drum heads engageable with apertures in said panels for removably securing the later, a continuously operating synchronous electric clock motor having the axis of its driven shaft transverse to the axis of said drum, and radially extending spokes mounted on the shafts of said drum and motor, said motor shaft being adapted to successively engage with the spokes of said drum shaft to impart to the latter a periodic rotation for successively registering said panels with said Window opening.
